This short chant comes from a Taiwanese VTuber clip shared online as a standalone reaction sound, with the creator tag nicawolper attached to the upload. Its appeal is the repetitive, sing song delivery rather than any actual phrase, so it spread in anime and streaming edits alongside similar cute vocal reactions like tuturu and anime ahh. Because it needs no context or translation, creators reuse it across Discord soundboards, short videos and livestream alerts whenever a moment calls for exaggerated cuteness or bewildered energy.
